How does buying items in bulk usually help a consumer?

Basically, you pay less when you buy in bulk. It's like you get a discount or offered a lesser price for the items because you bought a lot in number. Therefore, the consumer pays less per item. Once a consumer reaches a certain quantity of items, there is an introduced wholesale price which is a unit price lesser than usual which is already a big help to consumers.

Ironically, buying a lot at a time is cheaper than buying bit by bit. Places like Sam's Club specialise in having bulk supplies. People might not be planning to buy bulk, but after seeing how cheap it is, they'll decide to buy more than they planned. It creates the illusion of saving money to the consumer, but in reality, they spent more just because they liked the idea of getting more product. Hope that made since! :D

dusya [7]

Answer:

x=1, y=-1. (1, -1)

Step-by-step explanation:

2x-3y=5

x+2y=-1

---------------

2x-3y=5

-2(x+2y)=-2(-1)

-----------------------

2x-3y=5

-2x-4y=2

-------------

-7y=7

y=7/-7

y=-1

x+2(-1)=-1

x-2=-1

x=-1+2

There are some nickels, dimes, and quarters in a large piggy bank. For every 2 nickels there are 3 dimes. For every 2 dimes ther

rodikova [14]

Answer: a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.

b) The coins are worth of 91 dollars i.e. $91 in the piggy bank.

Explanation:

Since we have given that

For every 2 nickels there are 3 dimes ,

So, their ratio will be 2:3

and for every 2 dimes there are 5 quarters.\,

So, their ratio will be 2:5

Now, we'll first find the ratio of nickles to dimes to quarters i.e.

Nickle Dimes Quarters

2 3

2 5

So, it becomes ,

Nickle : Dimes : Quarters

2×2 : 3×2 : 3×5

4 : 6 : 15

Now, let the number of nickle be 4x

Let the number of dimes be 6x

Let the number of quarters be 15x

According to question,

$4x+6x+15x=500\\\\25x=500\\\\x=\frac{500}{25}=20$

So, number of nickels is given by

$4x=4\times 20=80$

Number of dimes is given by

$6x=4\times 20=120$

Number of quarters is given by

$15x=4\times 20=300$

As we know that

$1\ nickel=5\ cents\\\\1\ dime=10\ cents\\\\1\ quarter=25\ cents$

So, According to our question, we get

$80\times 5+120\times 10+300\times 25=400+1200+7500=9100\ cents\\\\1\ cent=0.01\ dollar\\\\9100\ cents=9100\times 0.01\ dollars=91\ dollars.$

Hence,

a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.

b) the coins are worth of 91 dollars i.e. $91 in the piggy bank.

Prove each of these identities.

Stella [2.4K]

Answer:

Identity (a) can be re-written as

$sec x\ cosec x - cot x = tan x$

which we already proven in another question, while for idenity (b)

$(A)\frac 1 {sin x} -sin x = cos x \frac{cos x}{sin x}\\\\(B)\frac {1-sin^2x}{sin x} = \frac {cos^2x} {sin x} \\\\(C) \frac {cos^2x}{sin x} =\frac {cos^2x} {sin x}$
